Make 'WordPress is better with Jetpack' bottom sheet text and button fully visible with big fonts

[ovitrif]

Fixes #17429

This PR fixes an issue preventing the text and button of the WordPress is better with Jetpack bottom sheet from being entirely visible on some devices with big fonts, by making the content of the bottom sheet scrollable.

To test:

Test Case 1 - Big Fonts

0. Prerequisite: Enable the jetpack_powered_bottom_sheet_remote_field feature flag.
1. Set max font size via Accessibility settings on device.
2. Tap the "Jetpack Powered" badge on Me, or My Site → Home
3. Expect to be able to scroll the content if it's not entirely visible on the screen
4. Rotate device to landscape (make sure Auto rotate is enabled)
5. Expect to be able to scroll the content.

Test Case 2 - Regression

1. Restore default font size via Accessibility settings on device.
2. Tap the "Jetpack Powered" badge on Me, or My Site → Home
3. Expect to see the WordPress is better with Jetpack styled as before, with no visual regression
4. Rotate device to landscape
5. Expect to see the WordPress is better with Jetpack styled as before, with no visual regression.

PR submission checklist:

• I have completed the Regression Notes.
